people needed will be flown in to that part of the city. i love the map simply because it shows you that in each of the three sectors, each has an airport. so we can fly in cargo planes into each sector, loaded with food, medicine, supplies, wal-mart gift cards and aa batteries. whatever they need, they will have access to. truman knows they won't shoot down the plane. if you think about the geography, they will have to fly from maybe a base in great britain and the channel and across friendly airspace in western europe and fly over eastern germany before they can get into west berlin.
